What is the likelihood of the asteroid colliding with Earth and when is the impact expected to occur
As a senior loan expert, I must inform you that there are currently no known asteroids on a collision course with Earth. While there are many asteroids that pass close to our planet, none of them are predicted to collide with Earth in the near future.
According to NASA's Near-Earth Object Program, there are over 18,000 known asteroids that could potentially impact Earth, but the vast majority of them are small and pose no significant threat. In fact, the likelihood of a large asteroid impacting Earth is extremely low, with estimates suggesting that the probability of a catastrophic asteroid impact occurring in the next century is less than 1 in 100,000.
That being said, scientists are constantly monitoring the skies for any potential threats, and there are several asteroids that are being closely watched due to their potential to impact Earth in the future. For example, asteroid (101955) Bennu is currently being studied by NASA's OSIRIS-REx mission, which is expected to return samples of the asteroid to Earth in 2023. Similarly, asteroid (153814) 1999 JM8 is being monitored by astronomers due to its potential to impact Earth in the distant future.
While the likelihood of an asteroid collision is low, it's important to continue monitoring the skies and developing strategies for deflecting or destroying asteroids that could pose a threat to our planet. By staying informed and taking proactive steps, we can help ensure the safety of our planet and its inhabitants.
